[PATCH v3 00/20] net-next: stmmac: add dwmac-sun8i ethernet driver

[Corentin Labbe <clabbe.montjoie@gmail.com>]

Hello

This patch series add the driver for dwmac-sun8i which handle the Ethernet MAC
present on Allwinner H3/H5/A83T/A64 SoCs.

This driver is the continuation of the sun8i-emac driver.
During the development, it appeared that in fact the hardware was a modified
version of some dwmac.
So the driver is now written as a glue driver for stmmac.

It supports 10/100/1000 Mbit/s speed with half/full duplex.
It can use an internal PHY (MII 10/100) or an external PHY
via RGMII/RMII.

This patch series enable the driver only for the H3/A64/H5 SoC since A83T
doesn't have the necessary clocks present in mainline.

The driver have been tested on the following boards:
- H3 Orange PI PC, BananaPI-M2+
- A64 Pine64, BananaPi-M64
- A83T BananaPI-M3

The first two patchs are some mandatory changes for letting dwmac-sun8i be used.
The following three patchs add the driver and its documentation.
The remaining are DT patch enabling it.

Changes since v2:
- corrected order of syscon compatible
- added compatible = "ethernet-phy-ieee802.3-c22 to PHY
- added set_mac function

Changes since v1:
- added TX/RX delay units
- splitted syscon documentation in its own patch
- regulator is now disabled after clk_prepare_enable(gmac->tx_clk) error
- Fixed a memory leak on mac_device_info
- Use now generic pin config for all DT stuff
- CONFIG_DWMAC_SUN8I is now set to y in defconfigs
